SPECIFICATION forming part of Letters Patent No. 661,105, dated November 6, 1900. Application led .Tilly 17, 1900. Serial No. 23,988. (No model.)

To all whom it may concern:

Be it known that I, CARL FRIEDRICH ML- LER, merchant, a subject of the Grand Duke of Hesse-Nassau, residing at Oppenheimer-y landstrasse 14,Fran kfort-on-the-Maine, in the Grand Duchy of Hesse-Nassau and Empire of Germany, have invented certain new and useful Improvements in Copying-Machines, ofA

which the following is a full, clear, and exact description. t

My invention relates to a copying-machine which diiers from other machines used for the same purpose by the simplification and effectiveness of its construct-ion in as far as its pressure or copying roller applying the letters or other originals to be copied upon the moistened copying-paper is pressed against the roller supporting this paper by organs of very si m ple and efficacious construction-11e., without using (as is the case in all other similar machines hitherto known or employed) india-rubber, springs, eccentrics, or other means. Moreover, inthe copying-machine embodying my invention the copying-paper is moistened in a manner allowing of a very accu rate adjustment by means of a receptacle containing the moistening-water absorbed by pieces of felt and easily to be moved against or from the moistening-roller by an eccentric connected with a ratchet-wheel and a pawl.

'lhe accompanying drawing represents a side elevational view of a copying-machine lembodying my invention.

In accordance with known construction my copying-machine shows side frames a, connected to each other by cross-pieces b to form .a complete frame, which is secured to a table, chest, or the like by means of bolts c. In this frame ythe organs existing also in other copyingmachines are disposed-viz., the lmoistening-.roller d, which is provided with a felt or other jacket well absorbing water and ,has secured to one of 4its journals e acranked ihandlefand two grooved pulleys g and h; the .advancing-roller i, driven from the said pulley h by a cord; the water-receptaclel, placed between the side frames a by means of pivtots m, engaging .in bearings fn; the roller o,

carrying the copying-paper; the vpressure or copying roller p, and the feeding-table q. The roller p is journaled in bearings r, sliding in guide-openings s, formed in the frames a of the machine and acted upon by screws t, entered in threaded holes provided in the said frames. In one of the latter a shaft u is supported below the water-receptacle Z, and this pivot has secured on its projecting ends a ratchet-wheel@ and an eccentric w, leaning against the bottom of the water-receptacle Z. A pawl w, engaging between the teeth of the ratchet-wheel c, is journaled on one frame a by means of a pivot y.

'Ihe effect and manipulation of the copyingmachine described in the foregoing are specied as follows: From the roller o the copying-paper is conducted in the way shown on the drawing by a thick line and inserted between the rollers (Z and p. Leaving the latter,the paper is passed around the advancingroller t' and led downward upon a reel, which is disposed in usual manner below the plate supporting the whole machine and driven by means of a crossed cordl receiving its movement from the grooved pulley d. Being rotated by the cranked handle f, the roller d takes up from the receptacle l a ,quantity of water, which may be easily regulated by conveniently turning and securing the eccentric w by means of the ratchet-wheel o and the pawl x. The letters or other originals to be copied are laid in usual manner upon the feeding-plate q for being inserted between the two rollers d and p. The latter being simply pressed as wanted against the moistening-roller d by means of the screws s, acting upon the sliding bearings fr, and the necessary adjustment ofthe water-receptacle being operated by the eccentric device, all characters hand or type written or printed with copying-ink, designs, drawings, &c. ,are transferred to the copying-paper in a complete, neat, and throughout equal manner.

What I claim, and desire to secure by Letters Patent, is-

In a copyingmachine, the combination with a frame, a water-receptacle hinged or pivoted at one end to the frame, and a moisengagingr tfhe ratchet-wheel, substantially as rening-roller, of a pressure-roller journaled in set forth. zo bearings mounted to slide in guides upon the In Witness whereof I subscribe my signaframe toward and from the mostxenngnoller, ture in presence of two witnesses. a shaft mounted upon the frame, zm'ecoen` tric mounted on Said shaft; and bearing upon the free end ofthe Water-Receptacle, a racchet- Wheel also mounted on said shaft and a pawl CARL FRIEDRICH MULLER.
